我想知道如何在通过单击时为 UIButton 设置动画
-(IBAction)
提前致谢!
在你的里面IBAction
UIButton *button = (UIButton*)sender;
//animates button 25 pixels right and 25 pixels down. Customize
CGRect newFrame = CGRectMake(button.frame.origin.x + 25, button.frame.origin.y + 25, button.frame.size.width, button.frame.size.height);
[UIView animateWithDuration:0.3f
delay:0.0f
options: UIViewAnimationOptionCurveLinear
animations:^{
[button setFrame:newFrame];
}
completion:nil];
编辑 - 在帧之间切换
在某处将布尔值初始化clicked
为 NO
if (!clicked){
//animates button 25 pixels right and 25 pixels down. Customize
CGRect newFrame = CGRectMake(button.frame.origin.x + 25, button.frame.origin.y + 25, button.frame.size.width, button.frame.size.height);
[UIView animateWithDuration:0.3f
delay:0.0f
options: UIViewAnimationOptionCurveLinear
animations:^{
[button setFrame:newFrame];
}
completion:nil];
clicked = YES;
} else {
//animates button 25 pixels left and 25 pixels up. Customize
CGRect newFrame = CGRectMake(button.frame.origin.x - 25, button.frame.origin.y - 25, button.frame.size.width, button.frame.size.height);
[UIView animateWithDuration:0.3f
delay:0.0f
options: UIViewAnimationOptionCurveLinear
animations:^{
[button setFrame:newFrame];
}
completion:nil];
clicked = NO;
}
